BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corrugated pillar material used for packaging articles and the like.

[0002]

2. Description of the Related Art A conventional corrugated fiberboard support member is long and cannot be folded and stored compactly, so that it has a drawback that it requires space for transportation and storage.

[0003]

DISCLOSURE OF THE INVENTION The present invention provides a corrugated cardboard support member that can be folded and stored compactly to save space for transportation and storage.

[0004]

In order to achieve the above-mentioned object, the present invention bends a corrugated cardboard sheet through a first fold line 11 in the step direction as shown in the drawing, and superposes them together to form a core material 10. A corrugated fiberboard support member in which a corrugated fiberboard cylinder 20 is externally fitted to the core material 10. The corrugated fiberboard sheet has a second fold line 12 intersecting with the first fold line 11.
And a cut line 21 is formed on the cylindrical body 20 over a part or the whole circumference in a circumferential direction at a position that does not coincide with the second fold line 12 of the core member 10 fitted therein. is there.

In the present invention, the step direction is a direction along a step peak or a step valley. It is usually appropriate to form about three first fold lines 11, but the number may be less than or more than this. Further, one second fold line 12 is usually formed, but it may be two or more.

The tubular body 20, as shown in FIGS. 1 and 2,
It may be configured by two or three or more cylinders in which a score line 21 is formed over the entire circumference in a circumferential direction at a position that does not coincide with the second fold line 12 of the internally fitted core material 10, and FIG. As shown in FIG. 1, one or a plurality of cylinders may be formed in which a cut line 21 is formed in a part of the circumferential direction (over three walls).

[0007]

Embodiment 1 An embodiment of the present invention is shown in FIGS. 1, 2 and 3.

In this example, the corrugated support material is made of one core material 1.
It is composed of 0 and two cylinders 20.

The corrugated cardboard sheet forming the core material 10 includes
Three first fold lines 11 in the step direction and one second fold line 12 orthogonal to the first fold line 11 are provided.

The tubular body 20 is made of two corrugated cardboard-shaped tubular bodies which are bent through the first fold line 11 and can be externally fitted to the core material 10 which is superposed. The cut line 21 formed over the entire circumference of the tubular body 20 is formed over the entire circumference in the circumferential direction at a position that does not match the second fold line 12 of the core material 10 when the core material 10 is fitted into the tubular body 20. Has been done. When forming the pillar material of this example, the fold line 12 of the core material 10 is extended, the fold line 11 is bent and overlapped, and the two tubular bodies 20 are externally fitted to the core material 10 from above and below, respectively. Butt the eyes 21. At this time, score line 2
Since the positions of the first fold line 12 and the first fold line 12 do not match, the first fold line 12 does not easily bend. Further, as shown in FIG. 5, if the product 30 is put in a tray-shaped box 41, four pillar materials of this example are erected at the four corners of the product, a cover box 42 is covered, and a band 43 is used for packing. Can be done quickly and easily. At the time of transportation and storage, as shown in FIGS. 6 and 7, the core material 10 in which the fold line 11 is extended is bent at the fold line 12, and the tubular body 20 is pressed as it is. Can be stored.

[0011]

Second Embodiment FIG. 4 shows another embodiment of the cylinder.

The cylindrical body 20B of the present example has a core member 10 fitted therein.
A score line 21B formed over three walls in a circumferential direction at a position that does not match the second fold line 12 (not shown) and 1
And a fold line 22B formed across the wall. When forming the pillar material of this example, the cylindrical body 20B is used.
The crease line 22B is stretched, and the core material 10 is internally fitted while the cut lines 21B formed over the three walls of the tubular body 20B are abutted. At this time, similarly to the first embodiment, the positions of the score line 21B and the second fold line 12 do not match,
It does not bend easily, and packing of heavy objects as shown in FIG. 5 can be performed quickly and easily. At the time of transportation and storage, as shown in FIG. 8, the tubular body 20B is folded in two along a crease line 22B, and the tubular body 20B divided into two as a boundary is overlapped and pressed. Can be stored in the box.

[0013]

When the cylindrical body 20 or 20B is fitted onto the core material 10,
Corrugated cardboard support is completed immediately, but the second core material 10
Fold line 12 and cut line 21 or 21 of tubular body 20 or 20B
Since the position does not coincide with B, the pillar material of the present invention is the core material 1
It does not bend from the second fold line 12 of 0 or the cut line 21 or 21B of the cylindrical body 20 or 20B.

[0014]

[Effect of the Invention] In the post member of the present invention, the second fold line of the core member and the cut line of the cylindrical member do not coincide with each other when the cylindrical member is fitted onto the core member, so that the supporting member can be easily bent along this. There is nothing to do. Further, since the length dimension can be shortened by easily folding the core material and the tubular body respectively, it is possible to save space in transportation and storage.
